i needed a pencil bag &didn't want to buy one unless it was hello kitty. So I made my own. It's not hello kitty, but I'm fine with it. I saved 7-10 bucks.
BY THE WAY! if you want to make one too, i don't suggest using felt because it get pretty ugly after a while, I call it "linty".

&also, i suggest using a thickish cotton fabric for the lining, i did not because i didn't have any. cotton isn't stretchy, so it's more sturdy.
